Activated carbon

Activated carbon adsorption material

Preparation and structural characteristics

Activated carbon is made from wood/coal raw materials through high temperature pyrolysis (600-900℃) and steam activation (800-1000℃). Its core features are as follows:

Pore structure

Specific surface area: 900-1500m²/g (BET method)

Pore Size Distribution:

Micropores (<2nm): >70% (main adsorption site)

Mesopores (2-50nm): contaminant transport channels

Physical form

Type Particle size range Iodine value (mg/g) Applicable scenarios

Powdered carbon 5-100μm ≥1000 Emergency water treatment

Granular carbon 0.5-4mm ≥950 Fixed bed filter

Pillared carbon Φ3-4mm ≥850 Industrial waste gas treatment

Water treatment core functions

■ Pollutant removal efficiency

Organic matter: benzene adsorption capacity ≥ 120mg/g (in accordance with GB/T 12496-2015)

Residual chlorine: catalytic reduction to <0.05mg/L (up to GB 5749-2022)

Odor substances: geosmin removal rate＞99.5%

■ Technical advantages

Adsorption rate constant: 10⁻³-10⁻² s⁻¹ (5 times faster than diatomaceous earth)

Acid and alkali tolerance: pH 2-11 working condition performance attenuation <10%

Adaptive filtration system

Equipment model Processing capacity (m³/h) Carbon layer height (mm) Target pollutants
